Fallout 3 Walkthrough & Strategy Guide

If it's not clear that there's a power struggle between Autumn and Eden by the time you get here, it will become clear once you arrive. Enclave Soldiers are gunned down by robotic sentries sent by Eden, who leave you alone. It seems John Henry Eden really wants to meet you, after all. But how does he have so much control over the robotic elements of the Enclave? You will soon find out.

Run forward down the corridor beyond where the Enclave soldiers were done in. This will lead to what appears to be a gigantic super computer that you can climb up. In fact, many staircases and catwalks will lead you higher and higher, further and further up, until you reach the top of the super computer. At this point, your first instinct will likely be running towards the door at the top of the stairs. But when you try to open it, you're unable to proceed. And then you hear John Henry Eden laugh and tell you to come look at him. But there's no one there! Wait just a minute...!

John Henry Eden, the president of the Enclave, the president of the United States, is a... a computer? Well my friends, you've now been exposed to one of the greatest secrets and spoiler points in the entire game. Congratulations! But now, it's time to engage this super-intelligent computer in conversation. It appears Eden has been alive and well since before the Chinese-US war destroyed the world. He was created for just such an occasion as a nuclear war, and has been ruling the Enclave and the remnants of the United States government for the better part of two-hundred years. We'll let you talk to him (at length) to get the rest of the information. And there's a lot of it. Keep in mind that your main objective after the conversation is over is to grab the FEV Vial before heading out the nearby door that was locked before. But with some persuasion and skill, you can convince Eden to destroy himself, which will make your escape from Raven Rock different than it would otherwise be. For the record, we here at IGN Guides convinced Eden through science that he must destroy himself. And he concurred.

It's time to make our great escape from the compound (which, for us, is being destroyed under our very feet since we convinced Eden to destroy himself). But President Eden is still very much plugged into the system, and his robotic Enclave friends will again assist you in getting out of dodge as quickly and as safely as possible. When you reach an office alcove, hack the computer if you can to free a powerful beast named Deathclaw, which you can then kill (as rapidly as you can) for massive experience. He packs a powerful punch, though, so be sure to down him as quickly and efficiently as you can! And comb the desk next to the computer for more items, including some healing items like a Stimpak.

Further down, the fray will intensify greatly. Gun turrets and mobile robotic units will do their best to nullify the human Enclave threat as much as possible (meaning, you shouldn't turn your ire on them as long as they're helping you), but they might not succeed in certain areas of getting rid of the threat completely, leaving a few half-damaged enemies for you to kill. Once they're dead, you can proceed forward, but be sure to check underneath the metal grating you're walking over via a staircase leading down, where a plethora of treasure chests lie in wait. Open them for all sorts of goods. Curative goods (Stimpaks, Dirty Water, RadAway, Rad-X and more) should be expected, but it's the myriad Plasma Mines, Plasma Grenades and Microfusion Cells that will really pique your interest.

Now, we're almost out of Raven Rock, but not quite yet. When you come across a light blue force field on your right as you're heading forward, you know you're headed in the right direction (though this entire area is completely linear, so getting lost shouldn't be much of an issue for you). There's going to be minimal help in taking out these last Enclave soldiers, and worse yet, they're decked out in powerful Tesla Armor and are toting, of all weapons, Missile Launchers. Quickly hack the computer so you can get through the force field. Grab the items you can (of most interest will be the Gatling Laser and Plasma Pistol), and then get ready to fight this final set of goons, concentrating on one at a time. The humongous amount of Stimpaks you've found (and likely already had) will come in handy here, since missiles do a number on your limbs. Take out these final foes and make sure to grab their Tesla Armor as you run outside.

The situation outside is hectic. You won't find any Enclave ground forces (thankfully), but if you were nice to the Super Mutant named Fawkes earlier in the game, he will be out here taking shots at the interesting helicopter craft the Enclave uses. Speaking of which, those helicopters are taking off en masse heading to an unknown destination. It seems like some sort of invasion force is brewing. What's going on!? Well, teleport instantly to the Brotherhood of Steel's stronghold at The Citadel to find out.

Once you arrive at The Citadel, you'll find it much the same way you left it when you took off earlier. But worry not, for even if things in the courtyard of the former Pentagon seem like business as usual, once you enter the building itself and head down into the laboratory, things are a little more hectic. Elder Lyons and her daughter, who heads the Brotherhood of Steel's elite unit (Lyon's Pride) are arguing over how to act next. And that's where you come in.

Until the Elder and Sarah begin talking to you directly, they don't know that the Enclave has the G.E.C.K. and can now effectively start Project Purity on their own at the Jefferson Memorial. Making matters worse, the Enclave has sent everything they had to protect that position and don't intend whatsoever to let it go without a fight. After either holding onto or giving away the FEV Virus (keeping in mind that the Brotherhood intends on destroying it after examining it), you'll be given an option by Sarah for some new armor (which you should decline, since you have Tesla Armor, much more powerful than whatever she's offering you). Then, when you're ready, speak to her again to begin the game's final mission.
